I showed a home this past weekend where the owner was smoking inside the house (full ashtray on the coffee table too). We waited while he put his three big dogs outside. Swirls of dog hair rolled along the floor inside. Outside, the dogs barked and stood up against a flimsy wire fence. We were all nervous.
